Description
Feature: Control chip: SSD1306Display area: 21.744 x 10864mmPhysical size: 27.3 x 27.8mmInterface type: Default 4-wire SPISwitchable rear resistor to use 3-wire SPI, IIC interfacesNumber of pins: 7Display color: yellow blueWorking temperature: -40~70°CNet weight: 5g Interface definition: 1> GND (Power ground)2> VCC (Power + 3.3-5V)3> D0 (SPI clock line for SPI interface and IIC clock line for IIC interface)4> D1 (SPI data line for SPI interface and IIC data line for IIC interface)5> RES (OLED reset, OLED needs to be reset once after power-on)6> DC (SPI data/command selection pin, used to set IIC address when IIC interface)7> CS (OLED SPI chip select, active low, if you do not want to use must be grounded) Package includes: 5 x 0.96 Inch OLED Display ModuleWiring method:
Wiring 1:MCU hardware SPI connection method:If there is only one device on the SPI bus, you can directly ground the CS of the OLED screen, which saves an IO.
Wiring 2:MCU IO analog SPI connection mode:If there is only one device on the SPI bus, you can directly ground the CS of the OLED screen, which saves an IO.
Wiring 3:MCU analog IIC connection method:IIC address:DC is low = 0x78DC is high = 0x7AGenerally DC grounding
Wiring 4:MCU hardware IIC connection method:IIC address:DC is low = 0x78DC is high = 0x7AGenerally DC grounding
